Airtac GFR Filter Regulator GFR400C15F1WK
The AirTAC GFR Filter Regulator GFR400C15F1WK is a genuine G-series filter regulator: water separation, 40 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has See datasheet ports, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.

About the Airtac GFR Filter Regulator GFR400C15F1WK
GFR400C15F1WK combines two decodable options on one AirTAC G-series filter regulator: the W 5 um filter element for finer particulate removal, and the K built-in reverse (check) valve that holds downstream pressure against supply dips or shut-off. The 400 frame carries a PT1/2 port, differential-pressure drain and an embedded square pressure gauge scaled in MPa, so it filters, regulates and holds in a single body.
It is a genuine AirTAC part. Maximum working pressure is 1.0 MPa (145 psi), the standard regulating range with the differential-pressure drain is 0.15-0.9 MPa (20-130 psi), and the working temperature range is -5 to 70 C (non-freezing). The 400-size bowl is polycarbonate. Related configurations - 200/300/600 frames, automatic or manual drains, the standard 40 um element, G (BSPP) or NPT threads and other gauge scales - are catalogue options within the same GFR family. Flow is published as curves, so we confirm datasheet and sizing figures on request.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). Air must not freeze in the unit. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

|---|---|
| C1 | Port size See datasheet. This body offers 10 = PT3/8", 15 = PT1/2". |
| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |

| (blank) | Pressure gauge fitted (blank). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |

Field order is size, port, drain, type, bracket, gauge, shape, scale, grade, thread, reflux — a blank position takes the default. Example: GFR300-08 is a 300 body, PT1/4", differential drain, standard type, bracket included, gauge fitted, 40 µm, PT thread, no reflux valve.

A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom. The GFR600 uses an aluminium-alloy bowl; the 200, 300 and 400 bodies use PC.

Where the Airtac GFR Filter Regulator GFR400C15F1WK Is Used
Leak-test stations
Regulated, filtered air for a pneumatic leak-test or proof-pressure bench, where the check valve helps hold the set pressure against upstream dips and the 5 um element protects the test circuit.
Laboratory test rigs
Clean, regulated actuation air for lab and pilot-scale test rigs, with 5 um filtration ahead of precision instruments and a gauge the operator can read in MPa.
Metered dispensing lines
Supply to a metered adhesive or sealant dispensing station: fine filtration protects the dosing valve, and the check valve holds circuit pressure if the upstream supply dips.
Is the Airtac GFR Filter Regulator GFR400C15F1WK the Right Unit?
The 400 frame with its 1/2 inch port suits 1/2 inch piping; step to GFR300 or GFR600 for smaller or larger circuits. W (5 um element) and K (reverse valve) are already specified on this code, so the remaining choices are drain type (differential-pressure standard, A automatic, M manual), gauge scale (1 MPa, 2 psi, 3 bar), thread (PT standard, G BSPP or NPT to order) and the J no-bracket version. AirTAC publishes flow as pressure-drop curves rather than a single rating, so send your line pressure and air demand and we will confirm sizing from the datasheet before you order.
Quick checklist
- ✓ Body size for your peak flow (See datasheet here)
- ✓ Element 40 µm or 5 µm
- ✓ Drain sets the regulating band
- ✓ Gauge fitted, shape and scale
- ✓ Thread PT, G (BSPP) or NPT
- ✓ Oil needed downstream? Use GFC instead
Installation & Maintenance Notes
- check Mount vertically, bowl down, following the airflow arrow.
- check One body does the filtering and the regulating — no separate regulator needed.
- check Keep inlet pressure at or below 1.0 MPa (145 psi).
- check Adjust only within 0.15 - 0.9 MPa (20 - 130 psi).
- check Drain condensate before the bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
Airtac GFR Filter Regulator GFR400C15F1WK FAQ
By curve, not by a single rating: AirTAC publishes G-series flow as pressure-drop curves, so we do not quote one rated number. Share your working pressure and air consumption and we will confirm the datasheet figures on request.
Yes - these are catalogue options, not modifications. The PT thread on GFR400C15F1WK is the standard; G (BSPP) and NPT are specified as suffixes, and the embedded square gauge can be ordered in psi (2) or bar (3) instead of MPa (1). An external round gauge is also available on the family.
